为什么UIScreen.bounds在iOS11中不正确 [英] Why are UIScreen.bounds incorrect in iOS11

问题描述

请不要将其标记为重复项.可用线程尚未提供答案.行为仅适用于iOS11.

使用现在的iOS11但仍使用Swift 3将项目从Xcode 8更新到Xcode 9，我有以下经验:

Updating a project from Xcode 8 to Xcode 9, using now iOS11 but still Swift 3, I have the following experience:

    print("UIScreen.main.bounds.width = \(UIScreen.main.bounds.width)")
    print("self.view.frame.width = \(self.view.frame.width)")

    let rect = CGRect(

        x: 0,
        y: 0,
        width: UIScreen.main.bounds.width,
        height: UIScreen.main.bounds.height * 0.25

    )

打印:

UIScreen.main.bounds.width = 414.0
self.view.frame.width = 600.0

该视图应该从屏幕边缘到屏幕边缘.因此，我使用了 UIScreen.main.bounds.width .但是对于 self.view.frame.width 的实际视图控制器大小而言，该值太小了.

The view is supposed to be from screen edge to screen edge. Therefore I have used UIScreen.main.bounds.width. But the value far too small for the actual view controller size of self.view.frame.width.

那是为什么?我想念什么?非常感谢您的帮助.

Why is that? What am I missing? Help is very appreciated.

物理设备.使用 UIScreen.main.bounds.width

推荐答案

我有一个类似的问题，错误地获取了 UIScreen.main.bounds 大小.尺寸小于物理屏幕.解决方案是将下一行添加到 info.plst :

I had a similar problem with incorrect fetching of UIScreen.main.bounds size. The size was less than a physical screen. The solution was to add the next line into info.plst:

键:

Launch screen interface file base name

类型:

String

值:

LaunchScreen

因此，请检查您的 info.plist ，看看其中是否包含此行.如果不是，则添加它.希望这可以帮助. info.plst的屏幕截图

So check your info.plist to see if it contains this line. If it's not, just add it. Hope this helps. screen shot of info.plst
